fix(ai): pertahankan status warn di cache moderasi + bersihkan prompt stale

Browse Source 
- normalizeStoredStatus(): exact-hash & semantic (Qdrant/PG) cache reader
  sebelumnya menipiskan 'warn' jadi 'flagged'/'clean' (type narrowing
  legacy clean|flagged) — merusak gating auto-delete & label dashboard.
  Kini status tersimpan dipertahankan penuh (clean/warn/flagged).
- prompts: hapus referensi <user_history> yang tak pernah di-inject,
  SearXNG -> Wikipedia (sudah migrasi), referensi section yang tak ada,
  typo 'secifik', dan baris list rusak '|-'.
- moderationBuilders: buang dead code buildUserProfilesBlock/
  buildUserProfileRef/UserProfileEntry/buildUserHistoryXml (tanpa caller
  produksi sejak context minimization) + test-nya.
- test baru: tests/storedStatusNormalization.test.ts (regresi warn).
